Castrol MAGNATEC Stop-Start 5W-30 is a semi-synthetic engine oil formulated with intelligent molecules which cling to the engine like a magnet and provide an extra layer of protection. Castrol MAGNATEC’s unique formulation means even once oil has drained away from critical components, these intelligent molecules will remain, protecting from the moment you turn the key and significantly reducing wear in stop-start operating conditions* commonly experienced in urban commutes. Today an average daily driver can stop and start as many as 18,000 times a year and all that idling in traffic causes microscopic wear in your engine.
*As tested in the industry OM646LA test.
Castrol MAGNATEC STOP-START 5W-30 is suitable for use in automotive petrol and diesel engines where the manufacturer recommends an API SN, ACEA A3/B4 or earlier specification 5W-30 lubricant.
